Plant Quiz: Flowers, Seeds And Sprouting

2.

We conducted some experiments: we put a pea seed in each of three pots; none of the pots had soil in them, they had a paper towel in the bottom. One pot we watered and put on the bench in the light. The second pot we watered, but kept in a dark cupboard. The third pot we kept in the light, but didn't water it.The pea seeds only sprouted in the first two pots. What can we infer (figure out) from this

Pea seeds need light, soil and water (moisture) to sprout
Pea seeds need light and soil to sprout
Pea seeds only need light to sprout
Pea seeds only need moisture to sprout

Correct Answer

A. Pea seeds only need moisture to sprout

Explanation

From the given information, we can infer that pea seeds only need moisture to sprout. This is because the seeds in the first pot, which was watered and placed in the light, sprouted. Similarly, the seeds in the second pot, which was also watered but kept in a dark cupboard, also sprouted. However, the seeds in the third pot, which was kept in the light but not watered, did not sprout. This suggests that while light and soil may be beneficial for sprouting, the essential requirement for pea seeds to sprout is moisture.

If we took three seeds and treated them differently as stated below, which would you expect to sprout? (They all get water and air).Seed A is kept at 50 degrees C Seed B is kept at room temperature (approx. 20 degrees C)Seed C is kept in the fridge at 4 degrees C

Seeds A and B
Seeds A and C
Only seed C
Only seed B

Correct Answer

A. Only seed B

Explanation

Seed B, which is kept at room temperature, would be expected to sprout. This is because most seeds require a specific temperature range for germination, and room temperature is generally within that range. Seed A, which is kept at a high temperature of 50 degrees C, is likely to be too hot for germination and may be damaged. Seed C, which is kept in the fridge at 4 degrees C, is likely to be too cold for germination and may remain dormant.

Which three things do seeds need to enable (let) them to sprout (put out plant parts)?

Moisture, light and air
Moisture, warmth and air
Moisture, cold and air
Light and air

Correct Answer

A. Moisture, warmth and air

Explanation

Seeds need moisture to soften the seed coat and activate enzymes for germination. Warmth is required to provide the optimal temperature for the enzymatic activity and metabolic processes involved in sprouting. Air is necessary for the exchange of gases, particularly oxygen, which is essential for cellular respiration during germination. Light is not mentioned as a requirement for seeds to sprout, so it is not one of the three things needed.

How is a seed produced?[HINT: check the wording of the question carefully - always do this in a test. It is easy to misread a question and give the wrong answer]

A seed is the product of pollen from the male part of a flower and the ovule inside the female part of a flower.
Seeds are found inside fruit, for example there are seeds inside a tomato
Seeds produce tiny little plants called 'seedlings'. This process is called 'sprouting'.
Seeds make new plants and can be spread around by wind, water or animals. This is called dispersal

Correct Answer

A. A seed is the product of pollen from the male part of a flower and the ovule inside the female part of a flower.

Explanation

A seed is produced through the process of pollination, where pollen from the male part of a flower fertilizes the ovule inside the female part of a flower. This fertilization results in the formation of a seed. Seeds can be found inside fruits, such as tomatoes, and when they are planted, they sprout into tiny plants called seedlings. Seeds also have the ability to be dispersed by wind, water, or animals, allowing them to produce new plants in different locations.

Tick ALL the statements that are involved in POLLINATION

Pollen sticks to a bee's hairy sides
The bee flies to another flower and the pollen rubs off on the sticky stigma (a female part) of the new flower
The pollen grows down the style (long female part) of the flower (this forms the 'pollen tube')
The pollen cell fuses with the ovule (egg cell) inside the ovary of the flower
A seed forms inside the ovary of the flower, and the ovary matures into a fruit

Correct Answer(s)

A. Pollen sticks to a bee's hairy sides
A. The bee flies to another flower and the pollen rubs off on the sticky stigma (a female part) of the new flower
A. The pollen grows down the style (long female part) of the flower (this forms the 'pollen tube')

Explanation

The statements involved in pollination are: pollen sticks to a bee's hairy sides, the bee flies to another flower and the pollen rubs off on the sticky stigma (a female part) of the new flower, and the pollen grows down the style (long female part) of the flower (this forms the 'pollen tube'). These statements describe the process of pollen transfer from one flower to another, which is essential for fertilization and the formation of seeds and fruits.

What is is called when a pollen cell fuses with an ovule (plants) or a sperm cell fuses with an ovum (animal egg)?

Mating
Courtship
Development
Fertilisation
Pollination

Correct Answer

A. Fertilisation

Explanation

Fertilisation is the process in which a pollen cell fuses with an ovule in plants or a sperm cell fuses with an ovum in animals. This fusion combines the genetic material from both parents, resulting in the formation of a zygote, which eventually develops into a new organism. Mating refers to the overall process of sexual reproduction, which includes fertilisation but also involves other behaviors and activities. Courtship is a specific behavior or ritual that animals engage in to attract a mate. Development refers to the growth and maturation of an organism after fertilisation. Pollination, on the other hand, is the transfer of pollen from the male reproductive organ to the female reproductive organ in plants.

Which of the following is/are a method of POLLINATION? (There may be more than one answer).

Wind (e.g. maize pollen blows over to the female flower parts)
Water (e.g. coconuts drift to new islands and sprout there)
Insect (e.g. bees transfer pollen to new flowers as they move around collecting nectar)

Correct Answer(s)

A. Wind (e.g. maize pollen blows over to the female flower parts)
A. Insect (e.g. bees transfer pollen to new flowers as they move around collecting nectar)

Explanation

B is NOT correct, because coconuts are a giant fruit with a giant seed in them - this is seed dispersal, not pollination.

Once a seed has formed, plants have to have a way to spread the seeds away from them so that they have room to grow. Which of the following is/are a method of SEED DISPERSAL? (There may be more than one answer).

Hooks (e.g. bidibids have tiny hooks on them and stick to passing animals or clothing like velcro, thus travelling long distances before falling off or being rubbed off)
Wind (e.g. grass seed is very light and gets blown away from the parent plant in a strong breeze)
Water (e.g. coconuts drift to new islands and sprout there)
Ingestion (the fruit of a plant gets eaten - ingested- and the fleshy part of the fruit is digested, whilst the hard seed gets passed out in animal poo ready to grow in a new location - fertiliser included free!)
Bee (bees put the seeds into the tiny sacks on their legs and carry them away to drop in new places)

Correct Answer(s)

A. Hooks (e.g. bidibids have tiny hooks on them and stick to passing animals or clothing like velcro, thus travelling long distances before falling off or being rubbed off)
A. Wind (e.g. grass seed is very light and gets blown away from the parent plant in a strong breeze)
A. Water (e.g. coconuts drift to new islands and sprout there)
A. Ingestion (the fruit of a plant gets eaten - ingested- and the fleshy part of the fruit is digested, whilst the hard seed gets passed out in animal poo ready to grow in a new location - fertiliser included free!)

Explanation

Plants need to disperse their seeds away from them to ensure they have enough space to grow. The given answer options explain different methods of seed dispersal. Hooks, such as bidibids, have tiny hooks on them that stick to passing animals or clothing, allowing them to travel long distances before falling off or being rubbed off. Wind dispersal occurs when lightweight seeds, like grass seeds, are blown away from the parent plant by a strong breeze. Water dispersal happens when seeds, like coconuts, drift to new islands and sprout there. Ingestion dispersal occurs when animals eat the fruit of a plant, digest the fleshy part, and pass out the hard seed in their feces, allowing it to grow in a new location.
